These would be the elements in row 2 the alkaline metals. Elements in a row usually share many qualities such as electon reactivity as well as similar characteristics like the fact that many alkaline metals are considered Cations, ions with positive charges. Some examples are beryllium and calcium.
Recombinant DNA is DNA that has been created using intelligent design methods to modify a base DNA molecule using DNA component elements from other strands of DNA of other organisms. There are a wide range of possible DNA elements that can be removed, added to or otherwise modified to produce the new recombinant form.
Recombinant DNA technology clearly is genetic engineering using intelligent design as the selection and placement of the added DNA components must be planned and precisely selected and placed to accomplish the intended result. It does not happen naturalistically.
There are numerous aspects of the growing technology of recombinant DNA that modify DNA to serve the purpose of the intelligent designers, including wide ranges of research, medicine, synthetic biology, potential commercial products and even scientific curiosity.
